Why are you guys so good at cricket? Is cricket really popular in Australia? Australia won 6 out of 13 World Cups and was the runner up in 2 other World Cups. That's straight-up dominance.
Unfortunately the world of cricket is smaller than one might like. As you can see only ten nations contested the 2023 World Cup and of those ten perhaps only half were ever plausibly candidates to take home the trophy. The great disappointment in world cricket over the previous generation has been the decline of the "West Indies" (mostly former British territories throughout the Caribbean) as a source of talent, and I believe this is attributed mostly to contemporary American sports offering better pathways and paychecks for players from those regions. On the other hand, the great success story in recent years is the rise of Afghanistan as a cricketing nation. Indeed, Afghanistan were very unlucky to lose to Australia a couple weeks back after having us on the ropes (we were saved by a double-century from Glenn Maxwell in what has been widely acknowledged as one of the most extraordinary individual performances in the history of international one-day cricket). If Afghanistan had won that match they could plausibly have gone on to feature in the semi-finals. It is a remarkable journey for a national team that has obviously been birthed under very difficult circumstances. That cricket has emerged as the dominant sport across the 2-billion people of South Asia gives it a secure future, but of course it would be nice for the sport to enjoy a broader geographic reach.
In Australia, cricket is not amongst the most popular sports (by most metrics that would be Australian Rules Football at the national level, or Rugby in NSW/QLD) but it has a certain prestige in the national culture that numbers alone do not reflect. There was a period of perhaps 15 years from mid-1990s to late 2000s in which Australia totally dominated all forms of international cricket. Over the past generation the financial centre of world cricket has moved progressively to India, particularly in the form of the Indian Premier League, and India has enjoyed great success in recent years with players forged in that great cauldron of talent. Hence this loss will have been particularly frustrating for India, as yet another loss to an old foe that has frustrated them on so many previous occasions, of a much-anticipated future failing to arrive.
If you are doing any reading about cricket it would do well to be aware that there are three basic forms of the game. The basics of bowling, batting, fielding, making runs and taking wickets remain the same across each format, but each requires a different balance of offensive and defensive tactics, mental resilience and player management, etc. such that it is not uncommon for individual players to find more success in one format than another.
"Twenty20" or "T20" Cricket: Each team plays 20 overs (delivers/faces 20x6 = 120 balls). Matches last ~3hrs. This is the IPL format.
One-Day Cricket: Most commonly, each team plays 50 overs, as in the "One-Day International" (ODI) format. Matches last for up to 8 hours, i.e. are concluded within a single day. The ICC Cricket World Cup uses this format.
First-Class or Test Cricket: This is the form of the game where matches can last 3-5 days. Unlike the previous two formats there is no hard cap on the number of overs. Typically, a series of matches are played over the course of weeks or even months. For example, Australia will shortly host Pakistan for a 3-test series with matches played 14-18 December, 26-30 December, 3-7 January.
